Connecting Fiber-Optic Cables to LC Ports

This section describes how to connect
• a 1000BASE‐SX multimode fiber‐optic segment from the network or other devices to
an LC port connector of a Mini‐GBIC (MGBIC‐LC01 or MGBIC‐LC03), or
• a 1000BASE‐LX single‐mode fiber‐optic segment from the network or other devices to
an LC port connector of a Mini‐GBIC (MGBIC‐LC09).
Each fiber‐optic link consists of two fiber‐optic strands within the cable:
• Transmit (TX)
• Receive (RX)
The transmit strand from a device port connects to the receive port of a fiber‐optic Gigabit
Ethernet device at the other end of the segment. The receive strand of the applicable LC
port connects to the transmit port of the fiber‐optic Gigabit Ethernet device.
Enterasys recommends labeling fiber‐optic cables to indicate receive and transmit ends.
Many cables are pre‐labeled, providing matching labels or tapes at both ends of each
strand of cable.
To connect an LC cable connector to a fixed LC connector of a Mini‐GBIC, refer to

Warning: Do not use optical instruments to view laser output. The use of optical
instruments to view laser output increases eye hazard.
Advertencia: No utilizar instrumentos opticos para ver el laser. El uso de instrumentos
opticos para ver el laser incrementa el riesgo de perdida de la vision.
Warnhinweis: Benutzen sie keinesfalls optische Hilfmittel, um die Funktion des Lasers zu
überprüfen, es könnte ihr Augenlicht gefährden.
3‐19 and proceed as follows:
Caution: Do not touch the ends of the fiber-optic strands, and do not let the ends come in
contact with dust, dirt, or other contaminants. Contamination of cable ends causes
problems in data transmissions. If the ends of the fiber-optic strands become
contaminated, use a canned duster to blow the surfaces clean. A fiber-port cleaning swab
saturated with optical-grade isopropyl alcohol may also be used to clean the ends.
Precaución: No toque los extremos de los cables de fibra óptica y evite su contacto con
el polvo, la suciedad o con cualquier otro contaminante. Si los extremos de los cables se
ensucian, es posible que la transmisión de datos se vea afectada. Si nota que los
extremos de los cables de fibra óptica se ensucian, utilice aire comprimido para limpiarlos.
También puede limpiarlos con un estropajo embebido en alcohol isopropílico.
